37mm UV Filter - Super Clear 24 Layers Multi Coated Ultraviolet Protection Lens Filter for DSLR Lens (Nano-Dazzle Series)

I noticed no difference in quality of my photos after I took this. I did take a lot of great photos after it was installed but I'm not sure if this cover would have much to do with that as I'm using it to simply better protect my lens.

I really love the quality, this screwed on my camera lens just fine (the very tip) without issue and I appreciated finding out the size was based on that little 0 symbol on the front of my lens. That's how I figured out I needed 67 mm.

Overall, really happy.

This is a well built UV filter. I got this to put on a non weather proofed lens with an internal zoom mechanism. Having a UV filter on the front will give that little extra protection from rain for an upcoming trip. The anodization on the metal ring seems to be of good quality. That, and the knurling on the outside ring offers very nice grip for installing or removing. The threading matches up with the threading on the lens well.

The filter glass is crystal clear. I found no noticeable degradation between shots taken with and without the filter mounted. When taking the same shot, in the same lighting, my camera did not adjust exposure values between having the UV filter on or off. This is a good UV filter for those of us that like having a little extra protection for our lenses.

Filter arrived well protected and seems to be a really good quality. I usually use Marumi, Hoya, and B+W filters, but this seems to be a great and more affordable alternative (at the time of this writing). Feels light but good construction. Nice ridges on the size to grab on for installation/removal.

Installed it on my Tamron 28-75mm lens that I use on Sony 7R III and after a few test shots I did not notice any distortion, flare, or other negative effects. Sharpness was not impacted either. Very happy with this filter so far. Will protect the lens and doesn't seem to have any impact on image quality. Will definitely check out other K&F filters.

Highest quality! Crystal clear. Smooth threading on lens with metal made ring... Thank you!

I have the 67mm on my Sony a7iii on my 85mm sony lens. It's so clear you don't even know it's on. The picture quality is the exact same without any issues. It blends in with the camera, yet saves your expensive lens from damaging. To assemble it, you turn it many times in a circle to tighten it on. No directions come with it, but pretty self explanatory. More information on their website. There's also a 1 year warranty period covered when you register the lens from the date of purchase. These can be replaced at a lot cheaper cost than having to repurchase your expensive lens!

While UV filters can improve your picture in some situations, most people buy them to protect their lens from splashes and dust without changing the image. This one seems good for that, it fits nicely on my sony 24-70 zoom lens and doesn't interfere with using either the lens hood or the original lens cap.

There is hardly any change in the amount of light that gets through to the camera and the UV filter can help to reduce atmospheric haze in long scenic shots and make the image a bit sharper.

This filter also has a water repellant coating, I haven't had to test this yet but if it works like the one on my glasses you won't have to wipe it if it gets wet. Any water that doesn't fall off immediately can be blown off with a hand blower so you don't have to touch the filter with a cloth.

I install a UV filter on all my lenses. Turns out my 70-300 was flying naked!! So I opted for this 67mm filter to protect the front elements. I do a lot of travel shooting as well as weddings and protection from bumps and such is key. It's far cheaper to replace a filter than a whole lens! This filter element offers a neutral pass-thru while protecting the front glass and threads of the expensive lens.

Recommended!

Today most of the benefit of a UV Haze filter is to protect the front element of a camera’s lens. There is some haze correction too but the film need for blue reduction isn’t a case with digital cameras. The bigger reason is that post processing software today has the ability to filter as much haze as the photographer wishes which is something no UV filter can do.

The need for protection is real. Even if it means keeping your lenses’ front elements from getting dirty or splashed, these filters play a role. I had this filter on when I took a misstep and splashed into a small river soaking the camera. I felt a good deal better about my clumsiness knowing that I’d not have to face the delicate job of lens cleaning when I got home.

However, a filter in the light path needs to be of high quality or it’ll degrade the image. I am far from having a lab where I can test glass here. The best test I thought up was simple. I’d take an identical image with and without the filter on and then compare to see if I caught any issues. Yes, it’s crude but it’s what I have.

Please see the included image. To create this, I placed the camera on a tripod, set the exposure manually as a best guess and then snapped two images – one with and one without this filter. I took the RAW images, arbitrarily cut a chunk from one and pasted it on the other. Both are labeled. I then compared the two concentrating on the area where they were joined. I’ve drawn a black line at the approximate location of the join. I did no post processing of any sort. These are the RAW (DNG) images directly from the camera only converted to JPEG for posting here.

I did my best pixel peek at both images finding no distortion whatsoever from this filter. In other words, it does just what I want and now has earned a place on my lens.

A UV lens is one that I recommend everyone have in their kit, especially if you like in very sunny but windy climates like I do. It really does help protect my lens from the debris flying around and just things in general. Photography isn't a cheap hobby/profession so taking a few dollars to invest in some protection is necessary. The fit of this is very tight, at first I didn't think it would fit properly but I just had to screw it on and off a few times before the threads slipped on with ease. These aren't super expensive which is great, but still do the job.

You never want to be without protection so its a good idea to always have an extra UV filter on hand! I have a couple others K&F including UV and polarizer and have no problem recommending. I saw no anomalies, flares or distortion. I would like brass mount but for the money these are perfect.
